Special Containment Procedures: SCP-1722 is to be housed in a standard storage locker within Site 19. No further security measures are necessary.

No written records or computers are permitted within the testing chamber outside of pre-approved testing materials. All data is to be transcribed from video after testing is completed. If tests require that a camera be brought within SCP-1722’s area of effect, staff overseeing testing are to communicate in American Sign Language.

Description: SCP-1722 is a branch of white oak measuring approximately 1.7 meters in length. SCP-1722 is decorated with various acrylic paints, colored duct tape, strips of leather, and feathers of the Canada goose (Branta canadensis). A partially completed string bracelet is attached to the item. Removed decorations have no anomalous properties of their own.

When SCP-1722 is held by a human subject, the contents of all physical and digital documents within a five meter radius will be permanently altered to contain handwritten commentary and proofreading notes, often in sufficient quantity to hinder the reading of the document. Video footage and audio recordings will be altered by the addition of a voice providing commentary, similar to edits made to texts. This voice is that of an adult male, estimated to be approximately 60 years of age.

No information contained within affected records will be deleted, and likewise no information will be added. Handwriting, vocabulary, syntax is consistent across all alterations.

Addendum-01: Notable commentary:

A speech written by ███████ ██████████, an 18th century member of the British parliament.

Look, now, you’re on the right track here, but just think about what you’re saying. Stomping down on the colonists is just going to get ugly for all parties involved. Best option would be to keep them as a semi-autonomous district, with a locally elected official serving as regional governor, accompanied by a second position who serves as representative in parliament. Also, knock it off with those curly fs. They’re annoying as shit to read.

Who the hell can’t store their own clothing? Like, are you literally so incompetent with those gigantic meaty lobster claws you call hands that you can’t figure out how to store and fold your own clothing? Really?

Wait what? Wait, what? Why is he doing this? Why is she doing that? What’s wrong with his arm? What’s wrong with her boobs? Who paid for this? Who paid money to read this? Why are they wearing tights in the arctic? Did this guy ever go to art school? What does this monologue even MEAN? Why does this exist? WHY?

You know what would be great? A flat rate sales tax. You get more tax revenue due to the lack of exceptions, it's already graded for wealth levels, and you get to gut ALL of the IRS.

Oh wait, America.

Oh look, it’s a guy with a stick. Wonderful, wonderful. Another guy walks in, “Hey Bob, how’s it going?” “Oh, you know, just holding this stick here.” “Oh really that sounds interesting! Here, hold this book.” “Gee wiz, Frank, now I’m holding both a stick and a book and aaaaaaaaaaaargh do something already!
